Chlorine (Cl2)
* State at room temperature: A greenish-yellow gas.
* Toxicity: Highly toxic and corrosive.
* Reactivity: Very reactive, readily forms compounds with other elements.
* Uses: Disinfectant, bleach, water treatment, production of other chemicals.
Sodium Chloride (NaCl)
* State at room temperature: A white, crystalline solid.
* Toxicity: Generally non-toxic in moderate amounts (table salt).
* Reactivity: Less reactive than chlorine, but still participates in chemical reactions.
* Uses: Table salt, food preservation, de-icing, industrial applications.
Key Differences:
* Chemical Composition: Chlorine is an element, while sodium chloride is a compound formed by the chemical bonding of sodium and chlorine.
* Physical State: Chlorine is a gas at room temperature, while sodium chloride is a solid.
* Toxicity: Chlorine is highly toxic, while sodium chloride is relatively safe in moderate amounts.
* Reactivity: Chlorine is much more reactive than sodium chloride.
In essence, chlorine is a dangerous gas that readily reacts with other substances, while sodium chloride is a common, stable compound used in many ways.
